ECG Machines Are A Life Saving Device January 19th, 2008

    ECG Machines are used to test patients for a variety of symptoms such as chest pain, breathing difficulty, and others. Depending on the reason for the test, a doctor may choose not to keep the patient at rest during the ECG. During an ECG exercise test, the patient must be supervised by not only the ECG technician, but also a medical doctor. Occasionally a patient participating in this test will have exercise induced chest pains. The pains will resolve when the exercise is stopped.

    Using the ECG along with other test, a doctor should be able to diagnose many diseases including coronary artery disease which is a condition where plaque builds up on the inside of the coronary arteries. This causes the heart to work harder to keep normal blood flow to all areas of the body, which changes the electrical impulses that an ECG measures.

    ECG measurements tell the doctor about the size and position of the heart chambers in addition to the rate and regularity of heartbeats. A doctor can also often see if any heart damage is present and how drugs or devices used to regulate the heart (such as a pacemaker) are effecting the heart.

    ECG Machines can be very expensive. Many hospitals buy used medical equipment to keep the costs down without risking safety. Places such as Absolutemed.com sell new and refurbished medical supplies online at reasonable costs.
